Randomized Controlled Trial Clinical Trial
Identification of low-effort patients through dynamometry.
In recent years researchers have devised a number of methods to detect patients who purposely exert low effort during grip evaluations. This study further defines the five-rung grip test introduced by Stokes and subsequently challenged by Niebuhr and Marion. New data are presented on the rapid exchange grip test. ⋯ No statistical difference between peak scores on five-rung and rapid exchange grip tests in sincere subjects was found. A statistical difference between peak scores in the low-effort groups was shown. A model has been developed that can be used to categorize patients into low effort or sincere groups.
